Robust attitude and position control remain critical challenges for consumer drones. This studies evaluates the performance of a Reinforcement Leaning algorithm (PPO) against traditional control algorithms on drone's stability in both computer simulation and real life situations. Reinforcement Learning is trained with common parameters and rewards for small attitude error, lower angular rates, and efficient control effort. Performance were measured across level 0 to 5 wind in simulation and level 0 to 3 in real life experimentation. Results showed that PPO out-performed traditional PID controller in both computer simulation and real life experimentation. PPO showed better stability than PID with reasonable actuation. These findings indicate that PPO can produce more robust, precise control than fixed-gain controllers.

This paper explores the dramatic function of monologues in Chinese and Western theater in the 20th century and earlier, with a focus on their role in character development and the depiction of psychological activity. Through an analysis of representative works such as Shakespeare's Hamlet and Cao Yu's Thunderstorm, this paper finds that monologues not only serve as an important means of revealing inner conflicts, but also play a central role in advancing the plot and deepening the expression of themes. In Western drama, monologues often carry philosophical reflections and self-examination, while in Chinese drama, they place greater emphasis on emotional expression and characterization through monologues. This difference in usage reflects the “cultural differences” between Chinese and Western drama in terms of narrative style and aesthetic concepts. Nevertheless, monologues still share the important function of expressing characters' emotions and revealing their personalities across different cultural contexts, reflecting the profound concern for the universality of human nature in dramatic art

This study examines the complex effects of social media on the mental health of adolescents in the digital age. Teenagers between the ages of 12 and 19 now live their lives heavily influenced by social media, which shapes their social interactions, identity formation, and mental health. Frequent use carries serious hazards, such as anxiety, depression, and cyberbullying, even though it offers chances for social interaction and assistance, especially for under-represented groups. According to empirical data, social comparison and body-image issues are exacerbated by algorithm-driven platforms like Instagram and TikTok, with adolescents who are insecurely attached being particularly susceptible to unfavourable comments. Unrealistic self-evaluations are fostered by excessive exposure to idealised content, which can lead to mental pain and, in severe cases, suicidal thoughts or self-harm. Psychological vulnerabilities are made worse by physical health problems, such as sleep disturbances brought on by extended screen time. The relationship between social media and teenage mental health is complicated overall, influenced by usage patterns, platform features, and individual differences, even when favourable outcomes—like peer support and decreased loneliness—are obvious. Generalisability is limited by methodological flaws in current research, such as the use of self-reported cross-sectional data and small, culturally limited groups. Nevertheless, findings highlight the urgent need for evidence-based interventions by parents, schools, and policymakers to mitigate risks and promote adolescents’ healthy development.

With the continuous progress and development of the times, the awakening of female consciousness and the struggles of women from all social strata have continued to advance. Increasing attention is being directed toward the awakening of women, and a growing number of literary and artistic works have begun to focus on this theme, portraying diverse, multidimensional, and richly nuanced female characters. This paper provides an in-depth analysis of three distinct female characters in Thunderstorm, exploring the awakening and resistance of female consciousness reflected in the work against the backdrop of its story and historical context. The differences in age, life experiences, personality, and cognition among these three women determine the varying degrees and forms of their awakening. By examining these three female characters, this study investigates the differences in the awakening of female consciousness across social classes and age groups under the historical conditions of the time. The awakening and resistance of female consciousness in Thunderstorm are complex manifestations that span multiple perspectives, levels, and social classes, rather than being concentrated in a single individual or event. Through a comprehensive analysis and study of the awakening and resistance of female consciousness in Thunderstorm, this paper aims to inspire reflections on the development of contemporary female consciousness and contribute to the exploration of solutions to the challenges faced by modern women.
